I agree your H is being very defensive and is obviously very angry......belongings in a bag left outside is a couple letters short of class (i'll let you guess which ones).
Even though you are not his ex wives, to him right now you are (whether it is justified or not). If he chooses to have an R talk I wouldn't have any plan other than to just listen, don't get defensive (even if you feel he is completely wrong) and try to see his perspective. If he wants to talk then he wants to be validated, even if it defies logic. You can always make a choice later on , that he is crazy or not worth it, but arguing or presenting your side will not bring you closer to him right now.
I hope it works out well, it sounds like you feel very frustrated and like you have been wrongly accused, which is probably the case.
As far as extending an olive branch, I would use which ever medium he has responded to the best in the past and chose the right time and place. Do you feel that your H has any major complaints that he has voiced?
